in the private network via the traversal server if there is an open connection through the
firewall.
A dedicated PathFinder server offers external endpoints a static address when joining
conferences hosted in your organization. You can dial 1234@pathfinder.company.com to
access from outside the firewall, or you can dial 1234 directly if you deployed the Scopia
®
PathFinder client.
Configure the PathFinder server as the XT Series's gatekeeper and enable H.460.
Figure 12: Using a separate NAT and Firewall Traversal Server
• Using the XT Series for NAT and firewall traversal
In cases where your organization has no sophisticated firewall protection, the XT Series can
straddle the two network zones using the both network ports provided on the XT Codec Unit
(see
Figure 13: Using XT Series for NAT and Firewall Traversal on page 29).
Activate the second network port with the correct license, then connect one port to the
public network and the other to your private network. All communication passes through the XT
Series which acts as the virtual conference room for all the endpoints.
